Slocum and Pearl of the Rio Grande — Jake Logan

Slocum sticks his neck out for a woman wronged. 

When Slocum meets lovely young Perla, he learns that the New Mexican woman's haughty manner masks fear. The Booster Brothers -- rustlers who raped and robbed her, killed women and children, and murdered her husband -- are leaving a trail of blood along the Rio Grande.
 
After Slocum agrees to escort Perla to her ranch, he takes another job -- as avenging angel. But before he brings the gang to justice, Slocum finds you ride one hell of a road to carry out good intentions.
